    I have a 2012 Cascadia with Cummins ISX15

    this morning I started my truck up and it gave me two fault codes

    Engine 000 SPN005394

    And

    Engine 000 SPN0003362

    Any help with these codes would be much appreciated. Thanks

    Don’t know what they are but chances are they are emission codes. Have you tried google searching those codes? If you got a Cummins, it’s best to get a inline 5 adapter with insite software to check your own codes and follow the trouble shooting trees. I’m not going to suggest eBay but it has worked for many/ the diagnostic software and etc that is

    Your flux capacitor needs more juice. At least 1.2 gigawatts.

    I googled them but nothing comes up. All I know is that it has something to do with the DEF Dosing.

    Dosing injectors are only a 200,000 mile service life.

    I appreciate the feedback. I’ll keep you posted. My main concern is getting back to Chicago so my mechanic can test it
